The Duke Defence Sonic Boom Grenade Refill Kit comes standard with a replacement sonic container, replacement pull ring and new 12g co2 canister. Reload the co2 into the core, slide the loaded core into the refill bottle, taking care not to cross-thread the bole, as it may cause the grenade to leak upon the next use, preventing correct operation.
